Audition Slow Recording

[Darkness]

Hi all,

 

I've had a strange problem with audition ive not had before. I was multitrack recording 17 channels. I used 2 echo audiofire 12s and daisy chained them to record a recent show so I can get a good audio mixdown to go on a video. I've done this before but with 1 audiofire and 12 channels and not had any problems. When I was doing some short test recordings I did not notice any problems.

 

When I got home to have a listen to the recording I noticed it sounded a bit odd, at first I thought it was just cause everything was flat as I was using the direct outs and pre fad and pre eq but when I listened a bit more closely I realised that the whole thing was just slightly slower than real time.

 

I want to put the audio onto a video so I need to get the speed back upto real time, I was wondering if anyone had any tips to get the audio back to the same speed as the video, I can see this being a right pain to sync with the video.

 

Also has anyone else experienced a similar problem, I guess it was down to the computer not being able to cope very well or could it be down to something else?

 

Thanks

Could be down to recording and playing back at different bit rates

I have this problem recording separate audio with a little Zoom handheld from my camera. When it comes down to the edit the audio is always a fraction too slow (about 1%).

 

Provided it didn't change speed half way through, find two hard edit points in both the picture and the audio, one at the start and one at the end of the piece. Line up the first one, then stretch the audio until the last one aligns.

 

I'm not sure if Audition has a stretching tool on the multi-track (shift drag an end handle, maybe, but you can do it with a bit of trial and error with the speed tool in any case. If you can do this for one track you should be able to apply the same transformation to every track.

 

Does that make sense?

I suspect Scatfish has the answer here. Differences in your settings between your record sample rate and the playback one (44.1 to 48 kHz maybe?) can result in exactly the effect you describe. If so, the fix is as simple as adjusting the playback sample rate.

 

If it turns out to be more than this, you might do better in a specialist Audition forum...I participate in and recommend the AUDIOMASTERS site.

I've had exactly the same thing when transferring some recordings from Minidisc to Audition (before I got the Zoom). It was to do with sample rate. I found I had to adjust it in the control panel of my soundcard (M-Audio 2496 and 1010), because it was defaulting to the wrong rate on playback. Very worrying at the time though as it was one of those "important" recordings.

 

A separate issue but related, there is some sort of bug in earlier versions of Audition (prior to v2 I believe) where in multitrack recording, if you use the "Pause" button between takes rather than Stop and Rec, some tracks slip relative to one another by around 194mS. That is a real nightmare to sort out once it's happened. Yep, had to do it.

 

Second Bobsy's point about Audiomasters - there's some real Aussie experts on there.

Thanks for the replies, when im next at the computer with the recording on I'll take a look at the sample rate. I know I had problems recording as the audiofire's set themselves to a 192Khz bit rate and audition wouldnt record with them so I did have to change them down to 44.1 I think.
